CERN Physicists Detect Liquid-like Properties in Quark-Gluon Plasma

Researchers at CERN's Large Hadron Collider, including MIT physicists, have found the clearest evidence that quark-gluon plasma, the matter of the early universe, behaves like a true liquid. By tracking individual quarks, they observed ripples, splashes, and swirling wakes, indicating a unified fluid response to fast-moving particles. This discovery significantly advances our understanding of the universe's earliest moments.
